Abstract: The present invention relates to a process for lignin dissolution in which partial methylolation of lignin is carried out during the step of preparing a solution of lignin in an aqueous medium comprising alkali and phenol. The lignin prepared according to the process of the present invention can be used to manufacture lignin-based phenolic resins, which are particularly useful in the manufacture of laminates.

Abstract: The present invention relates to a liquid lignin mixture comprising 3-50 wt% methanol, 12-50 wt% ligninand5-85 wt% aqueous alkali solution wherein the concentration of said aqueous alkali solution is 1 to 50 wt% of alkali in water, based on the weight of said alkali solution prior to mixing with the other components of the mixture. The liquid lignin mixture can be used to manufacture lignin-based phenolic resins, which are particularly useful in the manufacture of laminates.

Abstract: The present invention relates to an adhesive formulation comprising lignin, suitable for use in the manufacture of for example wood products.The lignin is provided in the form of a solution or dispersion or in dry solid form, such as in the form of a powder. The adhesive formulation also comprises phenol- formaldehyde (PF) resin and/or lignin-phenol-formaldehyde (LPF) resin. The adhesive formulation may also comprise extenders, hardeners, fillers and other additives, to achieve an adhesive formulation useful in the manufacture of for example wood products, such as plywood and laminated veneer lumber (LVL).The adhesive formulation can also be used in the manufacture of laminates and oriented strand boards.

Abstract: The present invention relates to the use of a bonding resin prepared by providing an aqueous solution comprising at least one biobased product selected from tannin, starch, soy protein, glycerol, chitin, pectin, dextrose or other carbohydrates, or a mixture thereof and mixing the aqueous solution with one or more of certain crosslinkers such as ethers, and optionally one or more additives. The bonding resin is used in the manufacture of laminates, mineral wool insulation or wood products, such as engineered wood products, such as plywood, oriented strandboard (OSB), laminated veneer lumber (LVL), medium density fiberboards (MDF), high density fiberboards (HDF) or particle boards. Preferably, the bonding resin does not comprise lignin.
